[Stability of myocardial perfusion during revascularization under propofol anesthesia]

During coronary artery bypass grafting surgery (CABGS) there are many factors which may disturb myocardial oxygen balance with consequent irreversible myocardial damage. Anesthesiologists are expected to use drugs with tendency to optimize hemodynamics and myocardial oxygen balance, making in that way conditions for preserving myocardial perfusion. In this study, performed on 19 patients undergoing CABGS under dominant propofol anesthesia, there were no signs of intraoperative ischemia manifested by statistically significant dislocation of ST segment in EKG leads D11, V5 and aVL.
